Stanis Idumbo
ASM
Set for spell on sidelines
Idumbo has been ruled out for Sunday's Ligue 1 clash against Lorient and for some time after suffering a psoas injury during Thursday's Conference League victory over CSKA Sofia, according to coach Filipe Luis, per Nice Matin. "Stanis has injured his psoas and will be out for some time. I don't think it's the same injury as before, even though it's in the same area."
Analysis: Idumbo has suffered another injury setback shortly after recovering from a groin problem that had previously kept him sidelined. The winger returned to action against CSKA Sofia on Thursday and delivered an assist before being forced off in the 64th minute due to discomfort. Further assessments have now revealed a psoas injury, with manager Luis confirming that Idumbo will miss an extended period, although the exact recovery timeline remains uncertain. The manager suggested that the latest issue is different from his previous injury despite affecting a similar area, raising concerns about the winger's ability to maintain consistent fitness. Idumbo's absence will reduce Monaco's attacking options on the left flank, with Mathys Detourbet and Ansu Fati likely to benefit from additional playing time while he recovers.
Could have suffered setback
Idumbo was forced to exit Thursday's UEFA Conference League win over CSKA Sofia due to a slight physical discomfort, with a new injury not confirmed yet, per Leopardsactu.
Analysis: Idumbo had just recovered from a groin problem and impressed with an assist in the European clash, so the team will hope he avoids another concern following his withdrawal. If available, the winger would be in contention for a spot on the left flank with Mathys Detourbet and Ansu Fati. Those two players project as the main beneficiaries of playing time in case Idumbo is dealing with a considerable injury.
Cleared to return against Toulouse
Idumbo (groin) is available for Saturday's Ligue 1 clash against Toulouse after recovering from a psoas injury and returning to team training, according to coach Filipe Luis, per Nice Matin. "Stanis and Mamadou returned to training last week, so all the players are available, which is very good for us."
Analysis: Idumbo has completed his recovery after spending approximately three weeks sidelined with a muscular injury that also forced him to withdraw from his first international call-up with DR Congo. The attacking midfielder resumed team training last week and has now been cleared for Saturday's home matchup against Toulouse, putting him in contention to reclaim his starting role on the left wing. Idumbo enjoyed an impressive start to the campaign, scoring once across four Ligue 1 appearances while establishing himself as a regular under manager Luis. However, with Ansu Fati also returning from injury, Idumbo will face increased competition for minutes alongside Mathys Detourbet, potentially limiting his immediate workload.
Expected back against Toulouse
Idumbo is expected to return to contention for Saturday's clash against Toulouse after spending the international break recovering from a psoas injury, according to La Diagonale.
Analysis: Idumbo appears to be closing in on a comeback after spending roughly three weeks on the sidelines with the muscular issue, which also forced him to miss his first call-up with DR Congo. The attacking midfielder has enjoyed a breakout start to the campaign, establishing himself as a regular starter under new manager Filipe Luis and scoring once across four appearances. His recent return to team training puts him on track to reclaim his spot on the left wing against Toulouse, though he'll still face competition from Mathys Detourbet and Ansu Fati.
Back in team training
Idumbo (groin) was spotted back in team training in recent days, the club posted.
Analysis: Idumbo had been ruled out for around three weeks with a psoas injury, an absence that interrupted a strong start in which he had established himself as a regular starter on the left wing and scored once in four appearances. His return to team training puts him on track to be available again for Saturday's clash against Toulouse, with Mathys Detourbet and Ansu Fati having been the options to see increased opportunities on the left if he had to miss more time.
Out around three weeks
Idumbo (psoas) has been ruled out of Friday's clash against Lens and is expected to remain sidelined for around three weeks, according to La Diagonale.
Analysis: Idumbo has been diagnosed with a psoas injury after establishing himself as a regular starter on the left wing during the opening weeks of the season. The expected three-week absence should keep him sidelined until after the October international break, interrupting a start to the campaign that has seen him score once in four appearances. Mathys Detourbet could see increased opportunities on the left during his absence.
Doubtful with psoas discomfort
Idumbo is a doubt for Friday's clash against Lens due to psoas pain suffered after a stretch of consecutive matches, according to L'Equipe.
Analysis: Idumbo has established himself as an undisputed starter on the left wing for Monaco, scoring one goal in four appearances so far this season. If he is forced to miss time, Mathys Detourbet will likely start in his spot, with the club also monitoring potential returns for Ansu Fati and Folarin Balogun ahead of the match.
Scores winner against PSG
Idumbo scored one goal to go with two shots (one on goal) and one cross (zero accurate) in Friday's 2-1 win against Paris Saint-Germain.
Analysis: Idumbo scored the winner in the 72nd minute after beating Marquinhos before finishing past Matvey Safonov. He has now started three consecutive Ligue 1 matches while attempting at least two shots in each, showing a growing role in Monaco's attack. His two tackles won and four clearances also showed his ability to contribute without the ball, giving him value at both ends of the pitch.
Four shots in win
Idumbo generated four shots (one on goal), one cross (one accurate) and one chance created in Sunday's 2-0 win versus Marseille.
Analysis: Idumbo was Monaco's most active wide player in Sunday's 2-0 derby win, registering four shots including one on target and delivering one accurate cross as the Congolese teenager consistently threatened Marseille's back line before being replaced in the 85th minute. He won zero of his five duels but his direct running and willingness to take on opponents created the space that allowed Aleksandr Golovin and Paris Brunner to operate with greater freedom through the middle. Idumbo has now featured in both of Monaco's Ligue 1 fixtures and his energy and directness from the left flank are a consistent source of danger in new coach Filipe Luis' system.
Sees minutes in preseason
Idumbo (shoulder) took part in Saturday's offseason clash against Sporting CP.
Analysis: Idumbo has been sidelined from official action since February, as he was a regularly unused substitute before suffering the injury, which required surgery and left him out over the last few months. He'll continue to look for chances to regain confidence during preseason work, and he could eventually become a viable left-wing asset for a team that previously used Ansu Fati and Aleksandr Golovin in attacking midfield roles.
Set for shoulder surgery
Idumbo (shoulder) will undergo surgery and is ruled out for the remainder of the season, according to coach Sebastien Pocognoli.
Analysis: Idumbo had managed just 22 minutes of action in 2026 before the injury struck, making the season-ending news a limited but still unfortunate blow for Monaco. The midfielder contributed one goal and one assist across 164 Ligue 1 minutes this campaign, appearing eight times off the bench, and will now focus entirely on his recovery from surgery ahead of the 2026/27 season.
